Hi

I'm currently working on implementing vacuum compression on our gas wells, with a desired operating envelope ranging from -10 psig to 100 psig.

I would appreciate input from anyone with experience in vacuum compression applications. Specifically, I'm looking for guidance on the following:

1. Can a reciprocating compressor operate effectively within this pressure range?

2. What are the best practices for water separation in this context?

3. How to manage dew point to avoid condensation?

4. How can oxygen ingress be prevented in a vacuum compression setup?

5. Are there any documented case studies or references where a similar application has been successfully implemented?

Any insights, experiences, or references would be greatly appreciated.

Thank you in advance for your support!

HI Syed 

In my past in oil and gas we used both reciprocating and Rotary Sliding vane (Ro-FLO). Both applications he had an average of around 20inHg on suction of compressor. 

All the compressor stations had big oversized Seperators with demister pads inside to help with liquid slugs.  

Oxygen was something we were always battling because of old lines and leaks. 

In California because of aging formations most companies run vacuum on the casings. It Definity helped with production, you could see it when you lost a compressor.
